PATENT OFFICE ILLINOIS, AssIGNon, BY nnsNE ASSIGN- MENTS, TOTELETYPESETTEB CORPORATION, F CHICAGO, ILLINOIS, A CORPORATION OFDELAWARE Application led April 14,

The invention relates to selecting telegraphs and seeks to provideanimproved system and apparatus for rapidly effectingl the transmissionfrom one station and the recording at a distant station of code signalssuch as required for effecting the operation of a type-setting orcasting machine, and particularly a monotype machine that is controlledby a record strip ortapeperforated in accordance both withvcharactersignals, representing letters, numbers and punctuation marks, and alsojustiiication signals.

Further objects of the invention are to provide an improved transmitteradapted to be controlled by a perforated record strip such as is nowused with a monotype machine and an improved receiver or recordingperforator producing such a record strip, and also 'an improved code andsystem for use in connection with such apparatus.

In the `Inonotype system, the character signals are made up of thirtycomponents. Each signal comprises two components, one selected from onegroup of-iifteen and the other from another group of fifteen and thesesignals are represented on the tape by transverse rows of holes. Thereare two holes in each transverse row, `each of which occupies any one ofa group of fifteen possible punch positions disposed on opposite sidesof the center of the tape and which may be designated for convenience,the A and B groups. Certain justiication signals include an additionalthird component represented by a hole in a sixteenth position on the Bside of the record strip.

In accordance with the present invention the transmitting and receivingselectors which determine the signals sent and recorded respectively aredivided into A and B groups and separate sets of permutation members offour each are provided, one set for each group of selectors and suchmembers are adapted to be conditioned in different combinations torepresent the two elements or components of the signals. Also, an 8unitcode consisting of permutations of two different electrical conditionsextending through eight successive time intervals or units is utilized,each signal being divided into two sets of four units sELnc'riNGTELEGRAPH 1928. Serial No. 289,883.

in correspondence with the separate sets of permutation' members and thetwo components of the different signals. Provision is thus made forsending and recording the large number of diiferent signals requiredwith a comparatively short code. Means are also provided fortransmitting and recording the specialthree component justificationsignals without increasing the lengths of the other signals.

The improved transmitter and receiver employed are provided with motordriven distributors which are maintained in proper phase relation bystarting and stopping intervals or units which are transmitted by thesending distributor in vadvance of and following each code signal andwhich serve to initiate and arrest the receiving distributor at thebeginning and end respectively of each slgnal period. f

The foregoing and other features of the invention as hereinafter morefully set forth, are illustrated in the preferred form and arrangementin the accompanying drawings and more particularly pointed out in theappended claims.

In the drawings,

regular monotype keyboard peri'orator. This strip has longitudinal rowsof iieed holes at its opposite edges and is advanced step by stepthrough a guide 11 to bring its transverse rows ozt signal holes over aseries of transmitter selectors in the form o vertically disposed tapepins 12. 'llhe reduced ends of the pins extend into openings in the tapeguide 11 and in a lower guide bar 18 and an additional guide bar 141holds the pins against turning. f

individual springs 15 tend to lift the pins through the pertorations otthe tape when a common transverse resetting bar or bale 16 The latter ismounted on a horizontal shaft 1?' and is operated by a cam 18 on a maintransmitter shait 19.

The tape is advanced step by step by feed wheels 2O arranged below thepath oit the tape on a horizontal shaft 21 and the latter is actuatedfrom a cam 22 on the main shaft 19 through the medium ot a feed lever 23provided with a pawl 2li engaging a ratchet 25 on the iced shaft.

it the end oie each signal the cams 18 and 22 operate the resetting bale16 and the 'feed lever 28 to depress thel tape pins that have beenlifted, advance the tape to bring the next transverse row ot signalholes over the pins, and then permit the lifting movement ot thecorresponding pins.

As' stated, the tape has two holes in each transverse row disposed onopposite sides of the center thereof, there being fifteen possiblepositions on the 'tape Jfor each of such holes. rlhe tape pins arecorrespondingly divided into A andv B groups and one pin of each groupis lifted at each operation. i rll`here is also a third perforation inthe transverse rows representing certain jiustiication slg- ,nals whichpermits the lifting of an additional tape pin 12 in the B group.

Separate sets of permutation members 26a and 26?) are associatedrespectively with the two groups of tape pins and each set of four.members is adapted to be conditioned by the group of tape pinsassociated therewith in a corresponding number of differentcombinations. In the form shown, each set of permutation memberscomprises four plates or bars arranged one above the other and pivotedto swing on horizontal axes. The permutation bars or members arespring-held in normal position and the tape pins are provided with codelugs 27 for shifting' the members in different combinations when thepins are lifted. The transmitter shown is provided with a sunflowerdistributor and the permutation members 26 are provided with a Contact28 movable therewith and each arranged between frontand back contacts.

The distributor comprises a brush 29 mounted on the end of thetransmitter shaft 19 and arranged to successively connect a Series ofsegmental contacts with a ring consucceeding signal.

ressens tact 30 and the main line conductor 31 which extends through aline relay 82 (see Fig. 1) at the receiving station.

The main transmitter shaft 19 is driven from a continuously operatingmotor 33 through gearing 34 and a friction clutch 35. A stop-startdevice in the form of an armature lever 86 cooperates with a stop disk37 and, when engaged therewith, holds the transmitter shaft at rest withthe brush en* gaging the stop segment 38. 'lhe stopl and start segments38 and 39 are connected to the opposite pole-s of a divided line batteryLl0 and the segmental contacts 1 to l inclusive on the A side of thedistributor and 5 to 8 inclusive on the B side are variably connected tothe line battery by the corresponding sets et permutation members 2601Iand 265. As shown, the segments 1 to 6 inclusive are connected directlyto the corresponding permutation switches and the front and backContacts ot the latter are connected to the opposite poles of the linebattery. The segments Z and 8, which adect the transmisison of the lasttwo units or intervals of each code signal,

may be similarly connected to battery by thecorresponding switches, butpreferably they are connected to armature levers Zl1 having frontand'baclr battery contacts and operated by relays l12 which in turn areconnected to the corresponding permutation switches. Relays 12 areprovided with armature levers 43 which control a locking circuit `forthe relays from a local battery. This lockingy circuit is opened whenthe distributor brush 29 reaches or passes through its rest position bya cam il on the shaft 19 and which operates a releasing switch 45. Eachrevolution of the transmitting distributor from and back to its restposition, eliects the transmission of a signal comprising two li-unitpermutations of positive and negative impulses or so-calledv marking7and spacing pulses) in accordance with the setting of the groups ofpermutation members 26a and 2Gb, each signal being preceded and followedrespectively by uniform starting and stopping impulses of differentpolarity. The relays 41 which store the last two marking pulses affordample time for the restoring and resetting of the ermutation membersduring the latter portion of each signal period and before thetransmission of the first selecting unit of the Obviously, if desired,the signals may consist of permutations of current and no-current unitsor intervals.

The special tape pin 12 does not position the permutation switches.Instead, when it is operated by a third or additional hole in a row ofperforations of the tape, it lifts a bell crank lever 46 which normallyenga es a shoulder on the hub of a gear 47. The fitter is mounted on ashort shaft 48 which is driven, when the trip lever 46 is released bythe special tape pin 12', from the main shaft iii 19 by a frictionclutch 49 and a gear 50. The shaft 48 carries a cam 51 which operates abell crank lever 52 and the latter serves to disable or prevent thefeeding operation of the 'tape feed lever 23 and also serves whenshifted to engage a pair of normally open contacts 53. The latter asshown in Fig. l, are interposed in the ener izing circuit of a relay 54which is arrange to disconnect the main line conductor from thedistributor contacts and connect it directly to the markin side of theline battery. rlhe cam 51, whic is driven at half the speed of the maintransmitter shaft by the two-to-one gears 47 and 50, holds the cut-outlever 52 in shifted position only during the second half of itsrevolution. Hence, during the first half of the revolution of the cam,two i-unit permutations are transmitted as described under control ofthe two other tape pins which rise with the special tape pin l2. But atthe end of such signal, cut-out lever 52 is shifted to prevent the feedof the controlling tape and connect the line to the operating or markingside of the battery during the succeeding revolution of the distributorand a code signal consisting o all marking units or intervals istransmitted. At the end of this signal, the Y lever 52 is returned tonormal to permit the operation of the tape feed lever and again connectthe line to the distributor contacts.

The recording receiver has a continuously operating motor 55 whichdrives a distributor shaft 56 and an operating shaft 57 (see Figs. l2and 14) throughthe medium of sets of gears 58 and friction clutches 59.Startstop levers 60 icooperate with shouldered disks 61 on theseshafts/and are controlled by mag-Y nets 62 and 63 respectively so thateach shaft rotates through a single revolution when the correspondingstart magnet is operated. A distributor brush 64 on shaft 56 is arrangedto bridge a series of segments and a ring 65 `which is connected to thefront contact of the line relay 32. The tongue of the line relay isarranged to connect a local battery 66 to its front contact upon thereceipt of marking or operating signal units or intervals.

Magnet 62 is connected to segment 67 which is engaged in the normal orrest position of the brush 64 so that thelatter is initiated inoperation by the starting unit of each sighal and successivelyy engagesthe segments 1 to 8 inclusive during the corresponding permuta- I ablycomprises four notched bars, each longitudinally movable to either oneof two positions to selectively align their notches in a well-knownmanner. Preferably, the permutation bars are held in normal positionagainst the tension of shifting springs by latches 70 that are trippedby the selecting magnets 68. Restoring shift levers 71 operated by cams71a and 7 1?) on shaft 57,v are provided for re-engaging the bars withthe latches at the ends of the operation of each set. The alignment ofthe notches of the permutation bars determines the o erative setting ofone each of two groups o punch selectors 72a and 7 2b lduring eachsignal period. These selectors, in the form shown, are disposed inhorizontal position above the permutation bars and the operating shaftsand are pivotally connected at their rear ends to the upper ends of aset of levers 72. The y punch actuating bars or bales 78. The

punches are mounted in a block 79l which, together with an upper dieblock 80, forms a guide for a recording strip or tape 81. The

punch actuators are operated by cams 7 8a and 78?) on the shaft 57. l

Magnet 63 which controls the operating shaft 57 is operated by a brush82 which bridges contacts 83 interposed in its energizing circuit at theend of a,half revolution of the distributor or at the end of the settingof the permutation bars 69a. rlhe cams 73a,

7 8a, and 71a then operate the shifting, punch actuating, and restoringbars 73, 78and 71 of the A side of the recorder and efects'the operationof a selected punch in the A group. Also, since the cams 7311, 782'),and 716 are dsposed 180 degrees behind those of the A side, theysimilary effect the operation of one of the B punches after the settingof the permutation bars 696. Thus, the selecting and operating cyclesfor the two groups of recorders or punches overlap; that is to say,

lthe selection of one of the B punches is effected during the operationlof the selected recorder or punch of the A group, andthe selection of anA recorder can be eiectedby the initial v4unit permutation of thesucceeding signal during the operation ofthe B recorder selected by thepreceding si al.

. It is only necessary that the .operating s aftv 57 shall complete theoperation of both sides Vof the recorder in response to any signalbefore its controlling magnetis energized during the mid-portion of thesucceeding signal., The' record tape or strip 8l is advanced upon thereturn stroke of the B punch actuay f tor 79 y.b means of a springpressed dog 84 h D tem or method of sending and recording sigmounte onthe B punch actuator and arranged to engage a pin on the operating leverof a pawl and ratchet feed mechanism. No feeding movement of the tapehowever, is ei ected upon the operation of one of the A unches so thatthe holes successively formed y the A and B punches selected by eachsignal, are aligned in a single transverse row across the tape.

kThe transmission ot special three compo nent justification signals iserlected as described during two successive rotations of thedistributors, the irst rotation serving to select and e`ect theoperation oil one of thevA and then one. of the B punches, and thenadvance the record strip one step. During the succeeding rotation of thedistributors, the transmitting distributor is disconnected from the lineas described and the latter is so controlled by the magnet 54 that thetongue of the line relay is maintained against its front contact so thatall of the selecting magnets are operated. The resulting setting of theA and B permutation bars edects the selection only of the special punchcontroller or selector72 of the B group and which is arranged to eectthe operation of a special punch 77. The latter is forwardly oll'set asindicated in Fig. ll so that the hole punched thereby aligns with thepreviously formed A and B holes of the special justification signal.

The selector 72 is also provided at its end with a projecting pin 86which is arranged to disable or prevent the operation oit the dog 84C byengagin it and shifting it as shown in Fig. 2O so t -at there is nofeeding operation of the record strip after the operation ofthe specialpunch. 'llie arrangement described permits the .transmission andrecording of special three component signals without increasing thelengths of the periods required to send and record most ot the signalswhich consist of two components only.

As usual in start-stop telegraph systems, the operating motors aregovernor controlled to maintain uniform speeds oie the respectivesending and receiving distributors. Preferably the stop arml oi2 thesending distributor is held in operative position by a normallyenergized magnet 87, so that the sending distributor operatescontinuously and is not arrested in its normal position unless thecircuit of the magnet 87 is opened hy a switch 88. The latter can heoperated manually to start and stop the sending ol3 signals and also bya loop of the transmitter controlling tape 1() to prevent breaking ofthe tape as it is delivered to the automatic transmitter from a keyboardperorator. Preferably also, to insure the stop of the receivingdistributor at the end of each'signal and itsstarting in place with thesucceeding signal, it is driven at a speed slightly faster than thatoithe sending distributor.

rlhe invention provides an improved sysnals in accordance with a codecomprising thirty elements or components for the character signals, withan additional element for justification, by means of a relativelyshorter code comprising only eight elements, or ten, if the preferredstart-stop system is employed. lt is also noted that each completetransmittedsignal is compound and in etlect comprises two separatesignals or code combinations, one for each component of the originalcode.

The improved transmitter and recording perforator are simple andcompact, the parts being mounted on base boards 89 between side brackets90 and below the paths of the'tapes. But numerous changes may be madeWithout departure from the scope of the appended claims. y
